SMSPDs are superconducting nanowire single-photon detectors. Fermilab made a huge advance in developing quantum sensors to track high-energy particles and discover dark matter. SMSPDs, superconducting microwire single-photon detectors, intrigue particle physics researchers. This landmark study addresses them.

Technology: Why SMSPDs Matter

SMSPDs, ultrasensitive quantum sensors, are improving particle physics timing and detection. Future accelerator-based investigations that require precise particle identification and tracking may require these features.

Compared to older sensors, the study shows significant technology improvement. Modern microwires have a larger active area than superconducting nanowire single photon detectors. They are better for high-intensity colliders because their increased surface area makes tracking charged particles easier.

Sensor fabrication has also been optimized. Recent work at the CERN accelerator test beam facility used sensors made of thicker tungsten silicide sheet than before. The main premise is that a larger wire may absorb more energy from high-energy charged particles, improving time resolution and detection efficiency.

CERN Experiments and Muon Detection

The Fermilab study proved SMSPDs could detect single high-energy charged particles like protons, electrons, and pions. The CERN study builds on that. The new studies went farther by evaluating muon detection efficiency for the first time.

Muons are particularly popular among scientists worldwide. These particles allow scientists to study fundamental forces and particles better than other leptons due to their unique properties and 200 times heavier mass than electrons. The detection of muons with superconducting microwire single-photon detectors is a major advance for global consortia investigating a high-energy muon collider.

In future high-energy collider experiments, millions of events per second are expected. To handle this large amount of data, detectors must follow particles with increasing precision in space and time, and SMSPD sensors are suited for this.

Looking for Dark Matter

Even while tracking particles in colliders is the major goal, SMSPDs are equally vital in dark matter research. In the Journal of Instrumentation, project scientists presented the first full temperature-dependent analysis of an SMSPD sensor array. The array's suggested use in low-background dark matter detection tests reflects this new technology's “rapid pace” of development.

Current Fermilab News

Quantum Science Center (QSC) and Quantum Systems Accelerator collaboration has advanced scalable quantum computer fabrication. This is a major advance in quantum information science. Researchers from MIT Lincoln Laboratory and Fermilab collaborated to show the use of cryoelectronics to govern ion traps, a vital step toward large-scale quantum systems.

Scalability Issues in Ion-Trap Systems

As qubits, ion-trap quantum computers use charged atoms contained by electric or magnetic fields, which scientists respect. Long coherence times and high-fidelity operations make these systems excellent for quantum computing. Scaling these devices to millions of qubits for sophisticated, practical applications remains a huge problem.

Ion-trap systems use a complicated laser arrangement and lots of wire to connect room-temperature electronics and cryogenic ion traps. Due to space and noise constraints, this traditional design becomes less viable as ion numbers increase. Scientists are trying to bring qubit control techniques closer to avoid this.

New Method: In-Vacuum Cryoelectronics

Fermilab and MIT Lincoln Laboratory made a breakthrough by replacing room-temperature controllers with a cryogenic chip. The researchers placed ultra-low-power cryoelectronics near the ion traps to reduce thermal noise and boost sensitivity.

The Fermilab cryoelectronics circuits created for extremely low temperatures were employed in this proof-of-principle experiment. These circuits were tested at the MIT Lincoln Laboratory ion-trap platform to transfer ions, keep them in predefined locations, and calculate electronic noise. The researchers demonstrated that this hybrid technique can reliably regulate and manipulate ions in a tiny form factor.

Institutional Cooperation and Support

The co-integration of ion traps and deep cryogenic control circuits project was supported by two of the DOE's five National Quantum Information Science Research Centers. The Oak Ridge National Laboratory Quantum Science Center and Lawrence Berkeley National Laboratory Quantum Systems Accelerator organized and staffed the demonstration. QSA was led by Sandia and MIT Lincoln Laboratory.

The discovery advances ion-trap quantum computing with cutting-edge capabilities, according to Quantum Science Center director Travis Humble. Fermilab Microelectronics Division chief Farah Fahim believes low-power cryoelectronics in these devices could speed up quantum computer scaling and sustain tens of thousands of electrodes.

Lessons and Future Plans

The experiment succeeded, but it identified technological barriers that will drive future growth. Researchers observed that Fermilab transistors behaved differently in the colder MIT Lincoln Laboratory environment, which affected control circuit operating range. Future systems will need circuits to retain voltages for minutes or hours, not milliseconds.

Robert McConnell of MIT Lincoln Laboratory says this demonstration of small-form-factor, low-noise electronics provides the framework for future hybrid-integrated systems, but there are still big barriers to overcome before technology can be scaled up. Future research will focus on directly attaching electronics to ion-trap devices to improve performance and scale arrays.

Broader Fermilab Quantum Research Context

This discovery is part of Fermilab's high-tech and quantum research ecosystem. Recent projects include building a laser lab for the world's largest vertical atom interferometer (MAGIS-100) and creating an open-source hardware framework that uses AI to make rapid decisions. Fermilab and NYU Langone Health are developing quantum computing-based quantitative MRI technologies.

UChicago quantum computing

Chicago leads a scientific revolution again. Enrico Fermi conducted the first sustained nuclear reaction there in 1942. This revolution is about exploiting quantum physics' strange and powerful principles to produce new information and computing systems, not dividing atoms. Private businesses are funding the Chicago Quantum Exchange (CQE) and collaborations with national laboratories like Argonne National Laboratory and Fermilab to turn decades of physics research into technologies that could change computing, communications, security, and even our daily lives.

CQE head and physics and molecular engineering professor David Awschalom says new technologies allow researchers to “engineer the way that matter behaves at the atomic scale.” This involves applying quantum laws, hitherto reserved for theorists, to real equipment.

Qubits can be a superposition of 0 and 1 at the same time or anywhere in between, replacing traditional bits' “0s” and “1s”. Many qubits can become "entangled," allowing them to send a single piece of information through space in unconventional ways.

Not just esoteric science. Awschalom believes quantum entanglement could enable safe interactions like credit card transfers without an intermediary. A quantum link would provide intrinsic security based on physics, unlike internet transfers that pass through hackable servers, routers, and repeaters.

In addition to security, quantum technologies improve computing, sensing, and navigation. According to Awschalom, quantum mechanics-based “miniature gyroscopes” could replace GPS satellites by harnessing Earth's magnetic field. This could help in flight, when signal interference and spoofing are becoming major difficulties. Additionally, tiny quantum computers could reduce the vast amount of electricity needed by present AI and supercomputers.

Lab-to-campus quantum ecosystem development Chicago's quantum goal's synchronicity is astounding. Beyond UChicago, the CQE has over 60 collaborators, including national labs, businesses, institutions, and research groups.

Most recently, momentum has grown. In November 2025, the U.S. Department of Energy renewed $125 million for Chicago's Q-NEXT and SQMS quantum-research facilities.

The quantum push is not limited to government-funded institutes. IonQ and UChicago announced a partnership to develop a campus IonQ Centre for Engineering and Science in November 2025. As part of the arrangement, IonQ will install an entanglement-distribution network and next-generation quantum computer at UChicago, making it one of the first institutions with production-grade quantum technology.

This mix of government, business, and academia shows a deliberate effort to accelerate translation of qubits from physics investigations to usable products for society. This is a new way for businesses, institutions, and national laboratories to work on new technologies to quickly move discoveries into society, according to Awschalom.

Along with infrastructure and research, the drive includes workforce development. Illinois already views good community schools as crucial for preparing people for the hundreds of thousands of high-tech jobs that could arise from “scalable atomic-size technologies” popularity.

What distinguishes Chicago? The legacy of risky research over chance

What's making Chicago a quantum computing hub? It's no coincidence. It began with Fermi's 1942 wartime nuclear reactor experiment at UChicago's football stadium. Making that option required ambition, bravery, and a willingness to let creative brains think beyond the box.

Awschalom moved from California to Chicago for its openness, inventiveness, resourcefulness, and risk-taking. Science needs varied, tolerant, and open-minded communities, unlike in the 1930s and 1940s, when many great scientists departed Europe.

Thus, Chicago quantum computer development goes beyond technology investment. It shows what happens when government agencies, institutions, labs, and corporations promise to help “the brightest,” regardless of background.

This has implications for society, technology, and the future.

Quantum endeavours in Chicago could revolutionise technology worldwide if successful. Possible effects:

Eavesdrop-proof communication networks: Entanglement-based quantum links can protect data exchanged between two locations, lowering government, healthcare, and financial sector communication vulnerabilities. Energy and processing efficiency: Tiny, specialised quantum computers might do complicated tasks like optimisation, cryptography, and materials research faster than classical supercomputers. This could reduce AI infrastructure's huge energy needs.

Quantum sensors can detect magnetic fields, chemical changes, and other events using qubits' specific features. This may enable satellite-free navigation or delicate medical investigations.

Scientific discoveries and economic growth: Technological advances in computing, materials science, quantum software, and other fields could create new industries, high-tech jobs, and international talent and investment in Chicago with strong funding and collaboration.

Humility underpins the lofty goal. Awschalom says this continues Fermi's work, but with information instead of energy on the atomic level.

He described qubits as “a miniature gyroscope you can spin in all three directions” that can be entangled to share “single bit of information.” If we accept quantum behavior's quirks and power, computing could change radically.

Conclusion:

Chicago is leading the atomic-to-quantum transition.

By 1942, Fermi and UChicago had revolutionized atomic science, physics, energy, and warfare worldwide. Ninety years later, the same university and location are positioning themselves to lead quantum information science, a distinct but potentially revolutionary discipline.

Chicago is becoming a global quantum powerhouse with the resuscitation of key research facilities, academic-business relationships, and a clear commitment to talent development and science application. In addition to formulas and experiments, the program promotes risk-taking, teamwork, and human contact as key to scientific progress.

Quantum computing, networks, and sensing could revolutionize computers, healthcare, secure communication, computing efficiency, and national infrastructure.
